MOLD FOR GLASS TILES FOR FLOORS, etc.

SPECIFICATION forming part of Letters Patent No. 286,984, dated October16, 1883.

Application filed March 24, 1883. (N model.)

To all whom, it may concern.-

Be it known that I, LAURIN D. WOODWORTH,

a citizen of the United States, residing at Youngstown, in the county ofMahoning and State of Ohio, have invented certain new and usefulImprovements in Molds for Glass Tiles for Floors, &c.; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in molds for the manufacture oftiles made of glass for floors, hearths, mantel-facings, and i 5 otheruses; and the object of my invention is to produce molds formanufacturing tiles of glass of any design or ornamentation, and suchtiles to interlock with each other and the cement in which they are laidor held in place. Said 2o tiles can be beautified and ornamented withany design upon either surface, or both, by

impressions from the mold or plunger, or by painting, or any othermanner of ornamentation known.

The invention consists in the construction and arrangement of molds,rings, and plum gers, by which glass tiles can be made of any suitableor desired design or configuration for floors, hearths, mantel-facings,other interior fittings, or any other purposes and it also consists insuch glass tiles as a new article of manufacture, all of which will bemore fully described hereinafter, and specifically pointed out in theclaims, reference being had to the accompanying drawings and the lettersof reference marked thereon.

In said drawings, Figure 1 represents aface' 'view of one of my improvedmolds. Fig. 2 is the ring for the same. Fig. 3 is a side view Fig. 4 isa detached perspective view of the pin attached to the lever for formingthe groove in the tiles. Fig. 5 is a bottom view of a tile made in theabove mold. Fig. 6 is a side view of the same.

Figs. 7 and 8 are modifications of said mold,

ring, and plunger, and the tile produced is intended for borders. Fig. 9represents-a section of a fioor orhearth. Fig. 10 shows a mantel-facing.Fig. 11 represents a face View of a mold for anotched tile; Fig. 12 is asimi- "lar view of a mold for tiles with the corners cut off by a rightline. Fig. 13 is alike view of a mold for tiles with the cornersindented by the segment of a circle. Fig. 14c is a view of a mold forcircular tiles. Figs. 15, 16, 17, 18, and 19 represent sections of, afloor or hearth embracing tiles made in molds shown in Figs. 11, 12, 13,and 14. Figs. 20, 21, 22, 25, 26, 27, and 28 are modifications of moldsfor different-shaped tiles. Figs. 23, 24., and 29 represent sections ofa floor or hearth composed of tiles made in the preceding molds.

In all of the figures of the drawings similar letters refer to likeparts.

In the drawings, the mold or base A is provided with the matrix a, thering-seat b, the pins 0, attached to lever d, and the handles 6, andtail-guide f. The levers d are pivoted at one side of the mold, as shownat g, and about midway of the mold the levers are pivoted to said moldby the pins 0, so that when the outer ends of the levers are movedinward the pins 0, which are preferably of dovetail cross-section, formthe groove h, largest at the bottom, directly across the flange of thetile, by which the tiles are held in place by the cement 011 which theyare laid. Suitable stops, 1 are secured to the levers d, which governtheir movement. The ringB is formed to fit the mold, and rests upon it.It is provided with the opening k, the dotted lines representing theshape of the matrix when the ring is in place, and the 1 space betweenthem and the edges representing the thickness of flanges that willappear upon the product. It has the handles Z preferably on the corners,and the lugs m, which extend outwardand downward, upon the outer edgesof the ring, to guide and hold the ring in place. The plunger 0 isprovided with lugs 02, which limit its descent through the ring B, andhead 0 serves to attach it to the press, in the ordinary manner. In Fig.4 is represented a perspective view, on an enlarged scale; of the pin 0for forming the dovetail recesses in the tiles, by which they are heldin place in the cement. 5 These pins are pivoted to the levers (I, so asto readily accommodate themselves to the move ment of the levers whenthey are forced in or drawn out from the molds. The walls of thematrices are as near perpendicular as will allow Ioo delivery, and areuniform in depth. The ringseat of the mold and the impinging part of thering are preferabl y fitted together, and the pl unger is fittedinto theopening of the ring, with the lugs adj usted so as to permit the face ofthe plunger to descend as far below the ring as is desired for the depthof the flange. The pins must fit perfectly into their seats, so thatthere 1 is no lost motion, and they can be varied in shape and size, aspreferred, the essential feature being that they are smallest at thesurface of the ring-seat. The inner edges of the ring B extend over thewalls of the matrix as far as desired for the thickness of the flange,which is preferably made about one-fourth of an inch, and the pins areprojected into the cavity of the mold precisely the distance of thisextension. The molds, rings, plungers, and pins with attachments aremade of iron or other metal, as glass molds for press-ware are usuallymade, and of suitable thickness at all points to maintain a propertemperature in working.

I have shown a variety of different-shaped molds, in which the matricesform various sizes and configurations of tiles; but in all of thesemolds the mold or base, the ring, the plunger, the pins, and levers aresimilar to those described in the first figures, and they will need nofurther description here.

In the remaining figures I have represented sections of hearths orfloors embracing the different shapes of glass tiles made in the moldsabove described, and they will require no further elucidation here. Iftransparent glass is used, and it is desired for beauty or protectionthat the tile be embellished upon the under side, the design is engravedor out upon the plunger; or the ornamentation may be applied to the tileby painting or other decorative art. If the ornamentation is to be uponthe upper side of the tile, as must be the case for opaque glasses, thedesign must be engraved or out upon or in the bottom of the matrix orthe tiles may be ornamented by art after they have left the oven orleer.

Excepting in the case where the ornamentation is on the under side ofthe tile, it is preferable to etch the upper surface, either by asand-blast or the use of fioric acid, so as to remove the polish and addbeauty to the tiles.

Any kind of glass may be used with good results, as the tiles so laytogether when in place that breakage by atmospheric action will notoccur; but I prefer, especially in hearths and mantle-fircings, to usethe best of lead-glass.

Ornamented in any manner in any of the popular designs, made of thevarious-eolored glasses, and tastefully laid, a floor, hearth, ormantel-facing made of the tiles exceeds all clay or encaustic tiles bothin beauty and durability, and can be made at much less expense, the softcement in which they are laid, embedded between the flanges and withinthe spaces formed by the pins, holds each firmly in place, so that noframework is required. The pins may be of ogec, curved, or other form incrosssection, but largest at the bottom.

The operation is as follows: The plunger is attached by means of itsneck to any ordinary glass-press having its power downward. The mold isplaced underneath and adjusted to its position by means of guides. Thering is then put in place upon the ring-seat of the mold, the pins 0 care pressed inward by the levers, and the gather of melted glass isdropped from a pontil into the cavity of the mold. The plunger is thencaused to descend by means of a lever upon the press into the ring,spreading the glass throughout the ma triX. The plunger is then raised,the pins drawn outward, and the product emptied from the mold and takento the leer or oven for an nealing.

Having thus described my invention, what I claim is- 1. Molds forpressing glass tiles, provided with one or more grooves or slots acrossthe ring-seat for a pin-bed, which is smallest at the surface of thering-seat, substantially as and for the purpose specified.
